for the process with hydrogen peroxide: 2 liters of H2O2 / Kg of CN in solution, during 4 hours. A flow chart and tables for the implementation of the process were designed. Keywords: gold mining; heavy metals removal; cyanide degradation; heavy metals.
Chapter 1 5 184.108.40.206 Placer mining Placer mining is used when the metal of interest is associated with sediment in a stream bed or floodplain. Bulldozers, dredges, or hydraulic jets of water (a process called ''hydraulic mining'') are used to extract the ore.

· The gold sludge was used to extract refined gold in the refining process. In the acid leaching/gold separation/reduction (ALSR) stage, a large amount of Hg was evaporated to gas. In the converter refining stage, the Hg release rate in the converter reached 99.7% due to the high smelting temperature of 1250–1400°C.
Yet mining the ore is just one stage in a long and complex gold mining process. Long before any gold can be extracted, significant exploration and development needs to take place, both to determine, as accurately as possible, the size of the deposit as well as how to extract and process the ore efficiently, safely and responsibly.

· If we have to know about gold assay, it is important to mention the Fire Assay Process that has been employed in the mining industry for a long time. Basically the ore is mixed with a mixture of fluxes and during the smelting process precious metals are liberated and most of heavy metals are trapped by the fluxes.
· A major source of air pollution from mercury, artisanal and small-scale gold mining releases approximately 400 metric tons of airborne elemental mercury each year. Located in over 55 countries, small scale gold buying and refining facilities (commonly referred to as "Gold Shops") are an important part of this production process, and are a major cause of air pollution from mercury.
The first part of the mining process involves finding the minerals. Exploration for gold and silver for modern mining in Waihi began in the 1970s and prospecting continued into the 1980s. Diamond drills bored into the ground at an angle of 45° and collected core samples from various depths. Approximately 13,000 metres of drilling was completed.
· At current gold prices this is worth about US$600. Both smelter treatment charges and oxidation or bio-leach costs are at least $200/t of concentrate and payables/recovery in the 90% range, so a minimum GSR for effective downstream processing is around 0.5. Clearly this is a function of gold price, but in the current gold price and cost ...

Despite a decline in global mercury consumption (global demand is less than half of 1980 levels), supply from competing sources and low prices, production of mercury from mining is still occurring in a number of countries. Spain, China, Kyrgyzstan and Algeria have dominated this activity in recent years, and several of the mines are state-owned.

Gold-Mercury Amalgam. Basically, amalgamation is the practice of bringing free gold particles into contact with mercury. When clean gold comes into contact with mercury, the two substances mix to form a compound called amalgam – an amalgam is simply an alloy of gold and mercury. The gold literally is dissolved into the mercury.
